What is considered a flood for insurance?

For insurance purposes, a flood occurs when water from a lake, river, creek, reservoir, canal or dam, or other natural watercourse covers normally dry land.

It’s important to note that flooding is different from storm damage or rainwater runoff, which occurs when heavy rainfall flows across normally dry ground, provided such rainwater is not combined with flood waters.

Flood cover typically offers financial protection for flooding that occurs from:

  • lakes
  • rivers
  • creeks
  • reservoirs
  • canals
  • dams.

Depending on your insurer and policy, rainwater runoff may be covered under storm cover rather than flood cover. Though some insurers won’t cover rainwater runoff when the customer chooses not to take flood cover.

To understand exactly how your insurer defines a flood and what is covered, read the relevant Product Disclosure Statement (PDS). Different insurers may apply different cover conditions, exclusions and benefits.

How much does home insurance with flood cover cost?

According to the Insurance Council of Australia, homeowners in flood-prone areas can face flood insurance costs of more than $7,000 a year, with premiums exceeding $30,000 for some properties in the highest-risk locations. The amount you’ll pay for home and contents insurance with flood cover is generally determined by the risk of flooding or water damage at your property, and the cost of repairing and rebuilding after a flood. As a result, your location could have a significant impact on your premiums.

Some other factors that may influence how much you pay for home insurance premiums include:

  • The type of cover you purchase.
  • Any optional extras you add to your policy, such as loss of rent and temporary accommodation and removal of debris.
  • The age of your home.
  • Property-specific information such as floor levels and construction type.
  • High repair and rebuilding costs following floods.

The excess amount on your policy could also impact your premiums. For example, opting for a higher excess on your cover could lower your premiums and vice versa. Before increasing your excess, ensure it’s an amount you can afford to pay if you need to make a claim.

How do flood cover claims work?

Flood insurance claims work like other home building insurance claims. After you lodge your claim, your insurer will contact you and may send a representative to assess the damage. If your claim is successful, you’ll receive a settlement from your insurance company. Your insurer may repair, rebuild or replace the damaged property, or provide a cash settlement up to your policy limits. The amount you receive will depend on your level of cover, your sum insured and any applicable excess.

If your claim was unsuccessful or you disagree with the settlement outcome, you can dispute this first with your insurer’s complaints resolution process and, then, if you are still unhappy with the outcome, through the Australian Financial Complaints Authority (AFCA) if necessary.
